When looking for a new case, you will most likely be focusing on a few key features that will stand out to you. Everyone is looking for a great quality case that is going to cool their entire system. Most people do not stop at just the quality of the case and how well it cools the system, they will be looking for the price vs. performance ratio, what comes with the case (Is there a power supply? How many fans?), and they will also be looking at how large the case is. Some people like large cases while some like smaller cases and for some, all they care about is how well the airflow is going to be. We will be taking a look at one of Sigma's cases named Atlantis, which seems to have a great classy, sleek design to it.
The Sigma company was formed back in 1988 and it has always been striving to be the best when it comes to meeting the customer's needs in terms of style and quality. The Sigma company is built on solid fundamentals and has the vision and capacity to further the computer gaming market. With Sigma's progression into the future, the company will forge ahead computer enthusiasts for the next generation. We will see how well Sigma is at doing this when it comes to the Atlantis.
When taking a look at the box that the case came in, you can tell that there are three different colors available, blue, silver, and black. Taking a look at the backside of the box, you can see some of the main features that Sigma wanted to point out.
When I opened up the box, I noticed that there was a a piece of styrofoam keeping the case from moving around during the shipping process. Also, the case was wrapped in a large plastic bag to keep scratches from occurring. Inside of the box, I found the case, a user manual, as well as a box that included a few bags of screws for different places in the case.
Just taking a look at the way the case is setup, you can tell that Sigma was aiming to make both a great looking case, as well as a case that will keep everything as cool as the surrounding air could keep it.
The front door of the case that swings open to the right hand side is held shut by a magnet. Opening this door reveals the four external 5.25" drive bays, as well as two exteral 3.25" drive bays.
Located below the front door, you can see where the 120mm blue LED fan is mounted. To the right hand side of the fan mount is where the power button, reset button, and power lights are located. To the left hand side of the fan mount is where you will find the front I/O panel.
Taking off the front cover allows you to see where all of the wires from the front go and how they make their way back to the interior of the case. This could help you when you are trying to hide some of your wires.
The bottom of the case has four legs that raise the case off of the surface that it's on, allowing you to get a better grip on it for movement. These feet have a rubber bottom to them so that you do not have to worry about scratching your desk, floor, or what ever else you may be placing the case on.
There is nothing special about the top, except for the fact that there are eight grooves to add a little bit of a design to the plain top. Some cases include a top exhaust fan, this one, however, does not.
Now let's take a look at what is located inside of this beautiful case.
The hard drive cage in this case is very interesting. There is a 120mm fan on one end, and if you remove the two thumb screws on either side, you then can pull a lever out and it unlocks cage, allowing it to be rotated. This feature could make the upgrade or addition of a hard drive easeier after the initial build has been completed. You wouldn't have to take the video card out of the case to be able to slide another drive into the cage this way.
The fans that were included with this case were manufactured by the Sigma company. There are two spots to mount 120mm fans on the side panel (fans are included), however with my Thermalright Ultra-120 Extreme, there was not enough room for the second fan, so I had to remove one.
There is another 120mm fan that was included with the case that is located above the rear I/O panel.
One of the most important parts of the case is also one of the simplest parts, the motherboard tray. This particular case's motherboard tray is stationary, meaning that it is not supposed to be removed and able put back into the case.
You can see from the back of the case how the tray is attached to the rest of the case and exactly how much room you actually have to be able to hide wires under it.
Now that we have taken a look at and understand how all of the features of this case work, we should begin to mount the components into the case and see how cool the case can keep them.
Every computer enthusiast enjoys putting together a new computer, or at least just installing the parts into a new case. Everything that I will be installing is listed below.
- Intel E6600
- Gigabyte GA-P35-DQ6
- 2x 1GB G.Skill DDR800
- ATI X1950Pro
- Lite-On DVD-RW
- Western Digital 320GB 16MB Cache SATA Hard Drive
- OCZ 700W GameXStream Power Supply
Let's get into the fun part of every build, actually putting the components into that bare and empty case. I started out by installing the motherboard riser screws. When you are doing this, make sure that you tighten them down as tight as you can get them with a pair of pliers. If you don't, there is a good chance that when you take your motherboard out, you could bring those risers out as well.
When it comes to the installation of the hard drive(s) in this case, you are in luck. As I had mentioned previously, the hard drive cage has the feature to rotate. This feature makes the installation of the hard drive a lot easier than in other cases as you do not have to worry about bumping other components previously installed in the case. All you need to do is remove the two thumb screws on either side of the cage, pull the tab out and rotate it. Then you can slide the hard drive into the appropriate slot, rotate it back to its original position and then screw it in.
After the hard drive was installed, I decided to install the motherboard. The heat sink that covers some of the I/O ports on the back of my motherboard caused a problem with the 120mm fan installed directly above it. After removing the fan, I was able to finish putting the motherboard in. For some reason, I was unable to get the motherboard's screw holes to line up with the riser screws, however after removing the back I/O panel cover, the holes lined up perfectly.
Once the motherboard was installed, I decided to move onto installing the power supply.
I then put the video card and the audio cards in and screwed them down.
After mounting the power supply and connecting the video card and audio card, the next logical step would be to connect all of the wires coming out of the power supply as well as the front I/O panel.
Now that everything is installed into the case, we are ready to boot it up to make sure that everything is working properly and run the appropriate testing to see how hot the installed components run.

To properly test this computer case, I will be testing for the idle temperatures as well as the full load temperatures. The way that I will be doing this is by letting the computer sit for 30 minutes at idle, recording the temperature, then running a one hour OCCT stress test with a blend of both CPU and RAM with a normal priority, then record those temperatures. I will be using SpeedFan Version 4.32 to gather my system chipset, CPU core, as well as the hard drive temperature readings. For the video card temperatures, I will be using ATI Tool Version 0.27's built in temperature monitor. To gather the full load temperatures of the GPU, I will be running 3D Mark 05 two times back to back, then quickly looking at the temperature reading.
- Intel E6600 @ 3240MHz (1000MHz OC)
- G. Skill DDR800 @ 850MHz 4-4-4-10-2T
- ATI Radeon X1950Pro (GPU @ 587MHz, Memory @ 770MHz)
- OCZ 700W GameXStream
- Western Digital 320GB 16MB Cache SATA
- Lite-on DVD-RW
- Sigma Atlantis (Case)
- Thermaltake Armour Extreme Edition (Case)
- Windows XP with Service Pack 2
I will be comparing the Atlantis to the Thermaltake Armour Extreme Edition with one rear 120mm fan, one rear 90mm fan, one Front 120mm fan, and one top 90mm fan. The Atlantis has four 120mm fans, I wonder how the temperatures will compare.
The Sigma Atlantis case is a nice mid-tower case. I was impressed when it came to the difference in the temperatures. The cores were only a few degrees higher in the Atlantis than my full-tower Armour, which I found amazing due to the size difference in the cases. The fact that the case was built out of a high quality aluminum was great as well as the actual looks of the case, which is one of the biggest things people look for when purchasing a new case. I liked how there were a total of four 120mm fans included with this case as not many cases come with that many fans, especially ones that large. The fact that there was no power supply included in this case could be a downside for someone new to the computer building scene, though for many enthusiasts, this wouldn't be a problem. During the installation phase of my review, I did run into a few problems. When I was attempting to mount the motherboard, the mounting holes on the motherboard would not line up with the motherboard risers. If you removed the rear I/O panel cover, the holes lined up perfectly. The other problem that I had was more specific to my particular motherboard; the heatsink located above the I/O ports on the motherboard was too tall for the 120mm rear exhaust fan. This problem, however, could be solved by removing the fan and mounting a smaller fan, such as an 80mm. Once past the minor hiccups specific to the hardware installed, the case performed admirably in comparison to the other case. If searching for a new case, keep this one in mind.
